‘Shoushan said to the assembly, “If you attain at the first phrase, you will be teacher of buddhas and patriarchs. If you attain at the second phrase, you will be teacher of humans and gods. If you attain at the third phrase, you cannot even save yourself.”
A monk asked, “At which phrase did you attain?”
Shoushan said, “The moon sets; midnight, going through the marketplace.”‘ (The Book of Serenity, case 76)
That monk has some cheek, but Shoushan doesn’t have to change gears to leave him in his wake. This is the koan that contains Baizhang’s, Yunmen’s and Chan Master Dao’s gems in the commentary.
